FURNAOE REGISTER.

`Application led July 20, 1925. Serial No. 441,657.v

This invention relates to improvements in furnace register constructionand more particularly to the mounting andoperation of the shutters ofthe register.v

rlhe furnace register to which this invention applies is constructedentirely of sheet metal parts and the invention provides novel means forpivotally mounting the shutters of the 'register without using` separatepivot pins but by forming the pivots from the metal of the frame.. Theoperating bar by which the shutters are actuated is also provided withnovel features of construction by which it is connected with theshutters. Various other novel features of construction and arrangementare also provided as hereinafter more fully described and particularlykpointed out in the claims, reference being had to the accompanyingdrawings, in which,

Fig. 1 is a plan view of a furnace register embodying this inventionwith parts removed and portions cut away.

Fig. 2 is agroup of fragmentary perspec tives showing various parts ofthe structure. Fig. 3 is a fragmentary sectional elevation of one endoftheV device on the line 3-3 of Fig. 1.

Fig. -1 is a fragmentary sectional elevation of the opposite end of thedevice on the line 4 1 of Fig. 1, and

Fig. 5 is a sectional elevation with a part broken out on the line 5 5of Fig. 1 su" stantially through `the axis of one of the shutters.

Like vnumbers refer to like parts in the different gures of thedrawings.

The furnace register has the substantially rectangular frame comprisingthe end members 1 and the side members 2, preferably joined at thecorners by electric welding. Tie bars 3 extend between the end members 1at spaced apart intervals to strengthen the frame and also to formsupports for the grating 4; which covers the frame.

The shutters 5, a plurality of which are located near the bottom of theframe, are pivotally mounted so that they may be moved from one positionto another to open or close the register. Each end member 1 y isprovided at its lower horizontal edge with an inwardly extending channelportion 6, the upper side 7 of which forms -a horizontal ledge. Pairs oflugs 8 are struck outward from the metal of the vertical face 9 of thechannel portion at intervals coinciding with the axis of each shutter 5,Ithese pairs of lugs 'being arranged closely together to approximate theshape of pivoty pins. Each shutter '5 has a corrugation or depression 10extending longitudinally at its axis'and an ear 11 and lever 12 bent Vupward at right angles at each of its respective ends. A hole 13 isprovided at the .base of each ear 11 and lever 12 of proper size toreceive a pair of lugs 8, av part of the hole coinciding with the saidcorrugation, and each lever 12 is provided with a slot 14, this slotpreferably extending angularly relative to the face of the shutters.

The operating bar 15, bywhich the shutters are simultaneously actuatedto rotate upon their axes, is located at one endof the register slidablysupported upon a ledge 7 between the end 1 and the levers 12. Therespective ends 1G of the bar 15 are preferably bent toward the end 1 tospacethe main body of the bar 2 from thevsaid end 1 which causes lessfriction in operation and also allows room for the pedal member 1.7 toextend between the bar 15 and the end 1 where it is attached to the bar.Lugs 18 are stamped at spaced apart intervals from the metal Vof theoperating bar and extend through the slots 14- in the levers 12.

of the shutters by constructing the device in this way is extremelycheap and c simple. The necessity of providing and attaching separatepivot pins is eliminated by forming substitutes for such pins by thepairs of lugs 8 which are struck from the metal of the ends of the frameduring lthe same operation by which the end of the frame itself isformed. Likewise the lugs 18 struck from the metal of the operating bar15 eliminate the necessity of separate pins or members for this purpose.The operating bar" 15 needs no separate retaining meansto hold it -inplace as it is supported upon the ledge It will tbe seen that thepivotal mounting The y ing rib and also has a proper curvature at therespective ends to conformA with the openings `13 through which the lugs8 o extend.

Ielaim: y y v l. Afurnace register comprising, a sheet metal frame,pairs of lugs stamped from the metal of the frame and projectingtherefrom, and shutters having openings each to receivevone of saidpairs of lugs and to be pivot-ally mounted thereon.

Y 2. A furnace register comprising, a sheet metal frame having-pairsoflugs stamped .from the metal oft-he frame and extending inward fromits respectiveends, and shutters each having an'- ear at each of itsrespective endsr each oi'r said ears being provided with an opening toreceive a -pair ofV lugs upon which the shutter is pivotally mounted.

3. A furnace register comprising, a sheet metal frame havingpairs oflugs stamped from the metal of the` frame and extending inwardly fromits respective ends, and shutters `each having a longitudinal corruga-`tion at its axis, and an ear4 at each end turnedupwardly from thedepression of the corrugation` and each ear having an opening at itsbase partly coinciding with said corrugation to receive one oi saidpairs of lugs y upon which the shutter is pivoted 4. A `furnaceregisterconiprising, a sheet metal frame having pairs of lugs stampedfrom the metal of the frame and extending inwardly from' its respectiveends, shutters located `between the ends of the frame and cach having anear at one end, and a lever metal frame having end members formed withinwardly extending horizontal ledges, pairs of lugs stamped from themetal of the frame at spaced apart intervals on the ends below theledges and projecting inwardly,

shutters, each having an ear at one end and tween one of said ends ofthe frame and the Y leversfof the shutters and slidably supported uponone of said ledges,and lugs stamped from the metal of the operating barand eX- tending into the slots of the leversl of the respectiveshutters.

6. A furnace register comprising,` a sheet nietal frame having pairs ,oflugs stamped i'roiii the metal of the frame and extending c5 inwardlyfrom `its respective `ends,an operi ating bar `,slidably' operated,parallel with y.

and adjacent one of said frameends and having a plurality of lugsStampedfrom the metal of said operating bar, shutters formed from asingle piece of `metal having ears turned on each end With'fholestherein' to receive said pairs of lugs `on which the shutter ispivot-ed, one ear having an extended portion with avslot'therein toreceive one of the lugs of the operating bar, by which the severalshutters are opened and closed simultaneoiisl y a 7. A iirnace registercomprising, a sheet metal frame havinglugs `extending inward iii-0in itsrespective ends and shutters each having a longitudinal corriigation atits axis and anear ateach endrturned upwardly from the depression of thecorrugation, and

each ear having an opening at its base partly coinciding with saidcorrugation to receive one of said lugs upon which theshutter ispivoted. y
